I have two internet gateways from 2 different service providers, the intention being that if one Internet Gateway went down then interent traffic would route thru the other gateway. I added persistent route statements to my PC (using route -p add cmd) and assigned a metric of 1 to the faster connection and and a metric of 10 to the slower one. In short if the Gateway with a metric of 1 goes down--it does not failover to the other Gateway. How can I rectify this?
Upon further investigation I have found the failover works on Windows XP boxes but NOT Vista and Windows 7. What the difference ?
